President Donald Trump on Monday said the U.S. would handle Oman “very easily” if it interferes in a potential deal over control of the Strait of Hormuz.

“I don’t think they behaved very well, but we’d handle them very easily,” Trump told reporters in the Oval Office when asked about comments he reportedly made earlier about Oman.

In a phone interview with Fox News’ chief foreign correspondent Trey Yingst about the Strait of Hormuz and Oman, Trump said, “If Oman gets in the way, we’ll bomb the s—- out of them,” according to Fox News.

Yingst relayed the quote from Trump on air, which he said came in response to questions over talks between Oman and Iran over the status of the strait. No audio of the interview was provided. The White House didn’t immediately respond to a request for comment about the remarks.

Oman, which borders Yemen, the United Arab Emirates and Saudi Arabia and is near the Strait of Hormuz, has been negotiating with Iran over the vital shipping route. Iran’s semi-official Mehr News Agency said Saturday that it had reached an agreement with Oman on a plan for traffic in the waterway.

Monday marks the end of a 60-day deadline that the U.S. and Iran agreed to in June to end the war and reach an agreement on Iran’s nuclear program.

Shipping traffic in the Strait of Hormuz nearly ground to a halt over the weekend, with just 13 ships passing through the waterway, including three on Sunday, according to maritime traffic tracker MarineTraffic.

Trump floated the idea last week of declaring the strait a U.S. territory. Asked Monday to elaborate on those remarks, the president said, “We have total control over the strait,” adding that a U.S.-imposed blockade “has been very effective.”

“Now maybe that will stop, or maybe it’ll open up even further,” he said. “But we’re taking out millions of barrels of oil a week. If you look at the kind of numbers that we’re doing … the strait is open, and the oil prices are coming down, and they will continue to come down unless we decide to do something far more drastic than we’re doing.”

As Trump made the comment, the international benchmark Brent crude oil broke above $90 per barrel and rose 2.7% to its highest level of the day.
